Abstract: Motivated by the convergence of terrestrial cellular networks and satellite communications, this article considers an adaptation of offset quadrature phase shift keying (OQPSK), ...
The system consists of two main components: TX (Transmitter): Encapsulates file data into framed packets, adds metadata headers, applies QPSK modulation, and transmits via SDR. An ADI PlutoSDR (AD9363 ...
Pulse density modulation (PDM) is a compact digital audio format used in devices like MEMS microphones and embedded systems. This compact primer eases you into the essentials of PDM audio. Let’s begin ...
Abstract: The increasing demand for data throughput in modern data centers has intensified the need for high-speed, energy-efficient optical interconnects. Although traditional intensity-modulation ...
